About this file
This document is an Attachment 1 specification sheet for two types of flexible vent ducting: Flex Tube Thermoplastic Rubber (TR-FR) and Flex Tube R-3 Blue (R-3), part of a naval shipyard procurement opportunity. The TR-FR product is a medium-weight co-extruded thermoplastic rubber hose with a rigid external polypropylene helix, available in 3", 4", 6", and 8" inside diameters, featuring fire retardant properties, ultra-smooth interior, high flexibility, and a temperature range of -60F to 275F. The R-3 Blue is a heavy-weight PVC hose reinforced with a coated spring steel wire helix, specifically an 8" inside diameter variant with a temperature range of 20F to 160F.
The specification requires all vent duct to be permanently marked "TR-FR" or "EF - FR" at every foot, with legibility being the primary marking requirement. This document is part of a solicitation (SPMYM325Q5029) by the Defense Logistics Agency Land and Maritime for vent ducting at Portsmouth Naval Shipyard, with a quote submission deadline of 6/18/2025. Vendors must submit quotes via email, include pricing, FOB point, CAGE code, contact information, and demonstrate capability to meet all specifications. The procurement allows quotes from approved vendors, with non-approved vendors required to submit sample and specification sheets.
